Metronidazole for Dogs Dose: What You Really Need to Know

If your dog is dealing with an infection or digestive issue, your vet might recommend metronidazole—a common antibiotic and anti-inflammatory medication for pets. But figuring out the right dose isn’t a one-size-fits-all kind of thing. The correct metronidazole dose depends on your dog’s weight, the condition being treated, and how severe it is. Getting it wrong can either make the medicine ineffective or cause unwanted side effects.

How Is Metronidazole Typically Dosed for Dogs?

Most vets dose metronidazole anywhere between 7.5 to 25 mg per pound of your dog’s body weight each day. Usually, it’s broken into two doses, taken about 12 hours apart. So, for a 20-pound dog, the daily dose could be between 150 and 500 mg divided over two times. The length of treatment is just as important and can vary from 5 days to a couple of weeks depending on the issue.

Always follow your vet’s exact instructions—don’t guess or cut the course short just because your pup is feeling better. Stopping early can lead to the infection bouncing back or stronger resistance.

What Conditions Are Treated With Metronidazole in Dogs?

Metronidazole is often used for bacterial infections in the gut, including diarrhea caused by Giardia and other parasites. It’s also prescribed for inflammatory bowel diseases and dental infections. Sometimes, vets use it alongside other meds to tackle complex infections.

Because metronidazole affects the dog's gut flora and nervous system, keeping an eye on side effects like vomiting, lethargy, or loss of appetite is crucial. If you see any unusual behavior, get in touch with your vet right away.

Metronidazole can be a powerful aid in treating your dog's infections, but only when dosed right and used carefully. Always consult your vet for personalized advice and never share human meds with your pet. With the proper dose and care, your furry friend can be back to their playful self in no time.
